BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to a contents consignment sale system andmethod for Internet broadcasting. More specifically, the presentinvention relates to a contents consignment sale system and method forInternet broadcasting for receiving sales consignments on authoredpieces from authors who have programs available for Internetbroadcasting, converting the pieces into a predetermined contents dataformat, providing them to Internet users so that they may select andstore desired contents in HDDs (hard disk drives), CDs (compact disks),or DVDs (digital versatile disks) according to their interests, andallowing the users to use the contents through an exclusive executionprogram. When a user desires to use the contents through the exclusiveexecution program, the system and method enable the user to receivepermission from an Internet broadcasting station and acquire restorationinformation corresponding to the contents through the Internet, so thatthe user may use the authored pieces.

(b) Description of the Related Art

Various categories of contents have been provided to users as theInternet has been recently developed, and the field with the most growthlatency among them is the entertainment industry, with the biggestmarket and the biggest growth potential thereof being the music andmovie industry.

Not long ago, Internet broadcasting stations provided small movingpicture services such as with the film size of 56K, and as high-speedInternet has recently been popularized they have attempted to providehigh-quality moving pictures with sizes such as about 300K or 500K. Thepicture quality, however, is worse than that of the DVD, and the imageand sound qualities are worse than those of general videotapes.

When many users concurrently use the moving pictures at the same time,the Internet performance speed becomes slower so that the movingpictures are stopped, the sound may howl, and signals may sometimes beinterrupted, thereby causing inconvenience to the user.

In particular, attempting to start a VOD (video on demand) business forreceiving fees is problematic, because the current Internet transmissionspeed and services cannot satisfy the users.

The reason for this is that the moving pictures available on theInternet are very inferior to DVDs and videotapes, and off-line serviceproviders already provide stereo and hi-fi videotapes and DVDs so thatusers may enjoy movies and music videos with high-quality images andsound data at any time they desire. Therefore, on-line movie rentalservices are not yet developed.

To activate a VOD business, service providers must provide high-qualityimage and sound services that are much better than the hi-fi stereovideotapes and equivalent to the qualities of the DVDs, compared to theconventional moving picture services of 300K or 500K currently beingprovided by the Internet broadcasting stations.

Nowadays, cellular phones and PDA's enabling wireless Internet servicesare on the market, and in the near future, multimedia terminals capableof wireless Internet will be commonly installed in cars.

In America, more than one million cars with multimedia terminals havebeen sold, but the speed of the current wireless Internet service ismuch slower than that of the wire Internet service, and in particular,the Internet speed becomes further slower and the Internet is oftendisconnected because of the unstable state of wireless radio waves whenthe car is moving.

Cell phones, PDAs, and vehicular multimedia terminals for providing thewireless Internet service for providing high-quality moving pictureswith quality images and sound data in fast moving cars have not yet beenproperly developed, but the wireless Internet services are involved inthe very initial steps by providing such things as an electronic mailservice and stock news, mainly for text communication with small datasize, and wireless Internet terminals are currently being sold.

The user does not have much difficulty in using general text informationsuch as email, stock information, or news on the wireless Internet whilethe user is moving, but in the case of attempting to receive a movingpicture service, it is required that the mobile station does not move atall but remains at a single place, or it may be moved at the slow speedof a person's normal walking. Currently, it is still difficult for theuser to receive high-quality image and sound services.

Further, the wireless Internet tends to have frequent interference byradio waves generated by various electronic home appliances such asradios, TVs, computers or cell phones, as well as cables, and the radiowaves may not easily propagate into a room in a building. Even when theradio waves enter a room, they may be easily reflected by a metallicdesk or a concrete wall to generate various problems, and hence it ismore difficult for the user to use the wireless Internet than the wireInternet, and the speed of the wireless Internet is slower than that ofthe wire Internet. In addition, in some cases, the user may not be ableto use the wireless Internet at all in a basement.

The communication speed when the mobile station remains motionless maybe faster according to the development of communication devices, but theabove-noted problems may not be completely solved because of thecharacteristics of the radio waves.

In particular, in the case the user uses the wireless Internetmultimedia terminal in a fast running car, since the multimedia terminalcannot fully receive the radio waves while the car is running fast, thedata transmission speed is greatly reduced. When the car passes througha tunnel or is on a street with many high buildings, turns around amountain, goes through a low place, or passes between concrete walls, orwhen another car or a motorcycle passes closely by the car, there issubstantial radio wave interference so that the user cannot receivevarious moving picture services such as quality movies, dramas, or musicvideos in the running car.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an Internetbroadcasting contents consignment sale system and method for receivingvarious authored pieces from authors as consignment, converting theminto specific contents data, allowing users to either freely downloadand save them or freely transmit the data to each other through areproduction process or the Internet, and enabling an Internetbroadcasting station to exhaustively and thoroughly control the users'using the contents so that they may use the corresponding authoredpieces with advertisements or for a fee.

It is another object of the present invention for high-speed Internetusers as well as low-speed Internet users to use high-quality movingpicture contents of premium image and sound data through an Internetbroadcasting station according to the present invention.

It is still another object of the present invention to implementmultimedia functions of quality image and sound through the wirelessInternet in a fast running vehicle without interference of instabilityof wireless signals or interruption of signals under bad wirelessInternet environments, wherein the Internet transmission speed isseverely reduced and signals are frequently interrupted by the user'smotion because of unstable states of wireless radio waves, andaccordingly the user can only receive a moving picture service when heremains still or walks very slowly.

In one aspect of the present invention, a network-broadcasting contentsconsignment sale system connected to authors for receiving a pluralityof authored pieces and providing the authored pieces to user terminals,comprises: a contents data management server for converting a contentsdata structure of the authored pieces into a predetermined format,transmitting converted data to the user terminal, and generatingrestoration information for restoring the converted data structure; adata storage unit for storing restoration information for restoring theconverted contents data; and a free-of-charge contents provider forproviding the converted contents data to the user terminal through anetwork or a free-of-charge distributor, and wherein the contents datamanagement server transmits the restoration information stored in thedata storage unit to the user terminal when the user terminal accessesthe contents data management server so that the contents data stored inthe user terminal are restored to original contents data and areexecuted.

The restoration information resides in the user terminal's RAM (or ittemporarily stored in a HDD depending on the contents), and therestoration information restores the converted contents data stored inthe user terminal into the contents data of before conversion so thatthe user may use the contents data, and when the restoration informationfinishes all tasks, the restoration information is automatically andimmediately deleted from the RAM or the HDD.

In another aspect of the present invention, in a network-broadcastingcontents consignment sale system for transmitting a plurality ofcontents data to a user terminal connected on the network, recording thecontents data on recording media including CD-ROMs or DVD-ROMs,distributing the contents data free of charge, and controlling users'using the contents data to obtain predetermined use fees from the users,a network-broadcasting contents consignment sale method comprises:converting the contents data's structure, separately generatingrestoration information (which selectively includes important data,editing codes, and numerical values, depending on the categories of thecontents), and storing the restoration information for executing theconverted contents data; transmitting the contents data having theconverted data structure to the user terminal via the network orrecording the contents data on various recording media including CD-ROMsor DVD-ROMs and distributing them to the user free of charge, when atransmission request on the contents data is input from the userterminal; and

transmitting restoration information (which selectively includesimportant data, editing codes, and numerical values, depending on thecategories of the contents) that corresponds to the contents data towhich a use allowance request is input, to the user terminal so that theuser may use the corresponding contents when the use allowance requestfor the contents data having the converted data structure is input fromthe user terminal.

The method further comprises transmitting advertisement data and therestoration information to the user terminal, and operating the userterminal to execute the contents and the advertisements, when the userselects to view the contents and the advertisements without paying theuse fee of the contents data.

In the case of unifying a plurality of network broadcasting stationsinto a single relay broadcasting system, a plurality of networkbroadcasting stations are combined into a single huge networkbroadcasting station, and each network broadcasting station is appliedas a single data storage unit. A relay broadcasting station isconfigured to manage all the members and uses in an integrated manner,and network users all over the world may use various contents providedby a plurality of member network broadcasting stations through a singlemembership entrance and perform fee settlement at a single homepage ofthe relay broadcasting station.

The relay broadcasting station provides technical support and useallowance for managing the above-noted relay broadcasting system, and itmay receive technical use fees from the network broadcasting stationsthat provide the contents, and use fees for the specific executionprogram from the users (members).

The relay broadcasting station provides the network broadcastingtechnique supports according to the present invention to a plurality ofnetwork broadcasting stations to allow the network broadcasting stationsof FIG. 2 to directly manage the network broadcasting, and to allow theusers to use the specific execution program of FIG. 3. The userregisters for a membership entrance of the relay broadcasting station soas to use and install a specific execution program, and when the useroperates the specific execution program, a user terminal initiallyaccesses the relay broadcasting station on the network to check whetherthe user is a registered member who has previously paid the membershipfee, and if so, the user terminal receives a use allowance on thespecific execution program to allow the user to access the networkbroadcasting station. The relay broadcasting station manages membershipof the users who use the specific execution program, and the relaybroadcasting station receives a predetermined amount of money from thenetwork broadcasting stations as broadcasting technical commissions eachmonth, and receives a predetermined amount of use fees from the users(members) each month to issue a program use allowance on the network, orreceives broadcasting technical commissions and program use fees fromthe network broadcasting stations and the users.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following detailed description, only the preferred embodiment ofthe invention has been shown and described, simply by way ofillustration of the best mode contemplated by the inventor(s) ofcarrying out the invention. As will be realized, the invention iscapable of modification in various obvious respects, all withoutdeparting from the invention. Accordingly, the drawings and descriptionare to be regarded as illustrative in nature, and not restrictive.

First, contents data provided on-line and off-line by an Internetbroadcasting station will be described.

The fast Internet contents data that netizens who use the wire orwireless fast Internet download on the Internet free of charge andwithout restriction and transmit to their friends on the Internet orthrough reproduction on a compact disc (CD), in other words, all kindsof entertainment data including movies, dramas, music videos, comics,children's picture stories, photos and photo albums, novels, andcomputer and video games, are generated as follows.

Moving picture data such as movies or music videos operate at 25 framesper second, that is, about 25 continuous pictures are shown for eachsecond of broadcast time. Comics, children's picture stories, novels,and photos and picture albums do not have continuous pictures, differingfrom the general moving pictures, but have still pictures or one-pagetexts for each page.

Hence, the present invention does not make comics, children's picturestories, and novels into still image data, but into a moving picturedata file format of 25 frames per second or 10 to 2 frames per second(in this instance, the number of the frames may be varied.)

For example, in the case of making one-page comics into one frame ofmoving picture data, 500-page comics are made into 500-frame movingpicture data. In other words, when the 500-page comics are made intomoving pictures of 25 frames per second, they will be 20-second movingpicture data, and if they are made into moving pictures of 2 frames persecond, they will be about 250-second moving picture data.

In addition to the above-noted method, the comics, the novels, and thechildren's picture stories may be made into still image data maintainingthe original format. In this instance, the contents may be used byscrambling the sequential order of the still image data to generateediting codes, by modifying numerical values of a predetermined portionof a picture data that configures a single still image, or by separatinga portion of data from the picture data file to generate restorationinformation and allowing the user to receive the restoration informationon-line and combine it with the converted contents data to generate thecontents of before conversion.

When the comics, children's picture stories, novels, and photos andpicture albums of a still image format are converted into moving picturefiles, the user is required to use the contents data frame by frameinstead of executing the contents at 25 frames per second or 2 framesper second, that is, executing the contents in 20 or 250 seconds once inthe like manner of execution of the general moving pictures.

Audio data may be stored in the children's picture stories, novels,comics, and photos and photo albums to output descriptions or narrativeon the picture histories.

When attempting to make the moving picture programs such as movies,music videos, dramas, comics, photos and picture albums, and novels intospecific contents data, an important portion is separated from theprogram data to form “an important data,” and the remaining data aredivided into dozens to thousands of units and scrambled in a randomorder to generate the “editing codes,” and the format of the data filesis converted into various formats so that the data files may not beexecuted through general programs.

It is desirable to modify the format of the various contents not by asingle method but in many different ways for the respective contents soas to prevent attacks by hackers. The specific execution programprovided by the Internet broadcasting station may use all theabove-noted converted formats.

In a different method, a single program is divided into dozens tothousands of units, the divided units are scrambled in a random order togenerate editing codes, predetermined portions are separated from therespective units to generate “an important data,” and the formats of thedata files are modified to become different each other.

The important data may include a predetermined portion of the contents,for example, a portion of the data of about 0.2 to 3 second running timefrom the data having the total running time of 10 seconds, or it mayinclude a portion of the actual data that forms audio signals or imagesignals.

In any of the above-described methods, if the separated data are notcombined with the remaining data, the converted contents data areincomplete, and hence the contents data are not executed through anyexecution program, and if combined, the converted contents data becomethe original data, that is, the contents data of before conversion.

It is required for the specific execution program to receive theseparated important data as restoration information that may be easilycombined, and when converting the converted contents data into theoriginal format and executing the same at the user terminal, it isrequired for the specific execution program to convert the contents datainto those of before conversion and execute them with no damage to theimage and sound qualities.

The formats of the contents data may be modified in many ways, and it isimportant to completely prevent the Internet users from using privateprograms or public programs for illegally using the contents data,instead of using the specific execution program provided by the Internetbroadcasting station according to the present invention.

Predetermined numerical values are applied to the various data values ofthe contents data to convert the data. The data include audio signals,image signals, and programs (in the case of video games or computergames), and it is important to convert the contents data, allow no userto use the contents data normally if the converted contents data are notconverted into the original format, and completely restore the contentsdata into those of before conversion using the restoration information.

In order to download various categories of contents data to the terminalon the Internet and execute them when they are stored in the terminal,the user uses the specific execution program to access the broadcastingstation according to the present invention, obtain a use allowance,determine whether to pay a use fee or view the contents together withadvertisements, and additionally receive restoration information(including editing codes, numerical values, and important data) forrestoring the contents data structure. In this case, the user receivesone, two, or three kinds of the above-noted restoration informationdepending on the categories of the contents.

When attempting to view the contents together with the advertisementswithout paying the use fee, the user receives the restorationinformation and customized advertisement data to view the advertisementsand the contents together.

The important data in the restoration information may be a single unit,but it is more desirable for the important data to include a pluralityof small data so as to increase effects of preventing reproduction.

For example, when moving picture data of a total of 90 minutes aredivided into 540 units, the running time of each unit is about 10seconds, and in this instance, the running time of one unit may be 8.12seconds in one case and it may be 11.84 seconds in another case. Asdescribed, the running time of each unit is randomly generated withinplus or minus 20 to 30%, and the important data are preferably generatedby separating the data that correspond to the amount of about 0.2 to 3seconds for each data of 10-second running time.

Hence, the specific execution program initially executes the contentsdata downloaded to the user terminal, and concurrently receives theimportant data via the Internet to temporarily store them in a RAM, andwhen a corresponding order comes, the specific execution programsupplements the contents data with the important data to execute thesupplemented contents data, then automatically deletes the importantdata from the RAM.I It previously receives important data of asubsequent order and stores them in the RAM, and when the correspondingorder comes, it supplements the important data of the subsequent orderto the contents data to execute the supplemented contents data. Inaddition, about 1 to 15 frames per 40 to 60 frames are separated as theimportant data for later use, and further modified methods may be usedaccording to the present invention.

When the specific execution program is executed, the user terminalobtains a use allowance, immediately receives the editing codes and thenumerical values on-line, stores them in the RAM, receives importantdata to be supplemented, stores them in the RAM, supplements theimportant data to the contents data to execute them in the proper order,and deletes the important data from the RAM, and in this case, thecategories and number of the restoration information (editing codes,numerical values, and important data) may be varied according to thecategories of the contents.

When the amount of the important data is too big to be temporarilystored in the RAM, the user terminal randomly selects a desireddirectory from a program that has many directories such as Windowsprograms or another desired one, converts the important data into ahidden file format, temporarily stores the same in the above-noteddirectory, shows them to the user when its proper order comes, andimmediately deletes the important data from the corresponding directory.

For further detailed description, the user terminal randomly stores theimportant data in any place and without any predetermined order anddeletes them after use, and it previously receives first important data,temporarily stores them in the HDD, and executes the specific executionprogram to show the important data to the user, and then deletes theshown important data from the HDD.I It subsequently receives secondimportant data, temporarily stores them in the HDD, shows them in theappropriate order, and deletes them, so that the user may not easilyfind the data and reproduce the same.

What is important in this case is that the important data preferablyreside in the RAM and are deleted in the default manner, and when theamount of the important data of the contents used by the user is too bigto be temporarily stored in the RAM and must accordingly be temporarilystored in the HDD, it is shown to the user in its appropriate order andthen deleted. Various kinds of restoration information including thecontents data, the important data, the editing codes, and the numericalvalues currently used by the user are not to concurrently reside in theuser terminal for more than 0.001 second, and therefore, it is requiredto divide the important data into many units.

In addition, programmers may modify the important data according tocorresponding environments in many ways.

What matters here is that the Internet broadcasting stations are toproduce and manage the contents data so that the user may execute themwhen the user receives restoration information on-line, in order for theInternet broadcasting stations to perfectly control the users all overthe world.

Second, in order for wire and wireless low-speed Internet users tofreely use the contents data, the Internet broadcasting stationsaccording to the present invention produce the contents data fortelephone modem users and low-speed Internet users, as follows.

The data that form a program are divided into dozens to thousands ofunits, the units are scrambled in a random order, and the format of thedata files is converted into an individual one. In this instance, thecontents data are converted by applying a predetermined numerical valueto the data values (including still image data and moving picture data),and this process may be possible or not depending on the contents.

It is desirable to allow no one to normally use the contents datawithout permission except when any user purposely damages the convertedaudio or image signals to convert them back into the original format.

To make the important data have a lesser size and better effects, a verysmall portion of the data that correspond to either or both of the imagesignals and the audio signals are separated to make them the importantdata.

Therefore, when attempting to use the contents data, the users use thespecific execution program to access the Internet broadcasting stationaccording to the present invention, checks membership status to obtain ause allowance, and determines whether to pay a use fee or view thecontents data together with the advertisements. In this instance, theuser is also required to receive the important data, the editing codes,and the numerical values for restoring the contents data structure. Whendesiring to view the advertisements instead of paying the use fee, theuser is required to receive corresponding advertisement data. Here, therestoration information includes one, two, or all of the important data,the editing codes, and the numerical values depending on the contents.As the categories of the restoration information increase, the functionfor protecting the contents data from hackers becomes better.

The Internet broadcasting station according to the present inventionrecords various contents data produced through a predetermined method onvarious recording media such as CD-ROMs, CD-RWs, DVD-ROMs, and DVD-RWs,and distributes them free of charge for promotion so that many users mayeasily use them. The Internet broadcasting station also allows andpromotes any kind of unauthorized reproduction of the contents data sothat the users may reproduce the contents free of charge and share themwith their friends without authorization

The Internet broadcasting station uploads high-speed Internet contentsdata and low-speed Internet contents data so that the low-speed Internetusers may also request their high-speed-Internet-using friends todownload various contents data for them, and thereby keep the contentsdata freely. The high-speed Internet users may use both high-speedInternet contents data and low-speed Internet contents data.

Third, in order for the high-speed and low-speed wire and wirelessInternet users to freely download and use various computer and videogames, and personal and business programs, the Internet broadcastingstation according to the present invention generates various programs,as follows.

A predetermined portion without which the program may not operate isseparated from the program, or predetermined numerical values of data inthe program are changed so that the program may not operate without ause allowance provided by the Internet broadcasting station. Therefore,to normally operate the program, it is required that dozens to hundredsof numerical values such as secret codes be supplemented, or that theseparated portion of the program be supplemented.

The program may be designed to operate when the numerical values or theseparated portion is supplemented, or preferably when both the numericalvalues and the separated portion are supplemented. The above-noted gameor business programs are designed to start their operation only with thespecific execution program provided by the Internet broadcasting stationaccording to the present invention, and the users are allowed to freelydownload the game programs and the business programs produced through aspecific method and keep them.

The Internet broadcasting station according to the present inventionrecords the business and game programs on various recording media suchas CD-ROMs and DVD-ROMs, and distributes them to many users free ofcharge. The Internet broadcasting station allows and promotes theunauthorized reproduction of the programs so that the business and gameprograms may be stored in the HDDs, the CD-ROMs, and the DVD-ROMs of theuser terminals.

Accordingly, when attempting to use the game and business programs, theuser is required to use the specific execution program to access theInternet broadcasting station, check membership status, obtain a useallowance, determine whether to pay a use fee or view advertisementstogether with contents, and receive on-line one or both predeterminednumerical values of data for restoring the converted program structureof the game programs and the business programs and a portion of theprogram, and when the user determines to view the advertisements withoutpaying the use fee, additionally receive the advertisement data to viewthe advertisement data together with the game program or the businessprogram.

In the process for generating restoration information, it is required toapply no routine to the process when dividing the contents data into aplurality of units and scrambling them to generate the editing codes,when separating the important data from the contents data and whenmodifying the numerical values. Namely, by differentiating therestoration information and the numerical values for the respectivecontents data, attacks by hackers who attempt to solve the convertedcontents data will be blocked.

FIG. 1 shows a block diagram of a contents consignment sale system forInternet broadcasting according to a preferred embodiment of the presentinvention.

An operation of the contents consignment sale system will now bedescribed.

First, the Internet broadcasting station 30 enters into a saleconsignment contract 20 with the authors 10 and 15, and converts theirauthored pieces into specific contents data.

The Internet broadcasting station 30 allows many users to freelydownload or receive the contents data wirelessly or through the wireInternet 50.

The Internet broadcasting station 30 also saves the specific contentsdata on recording media such as CD-ROMs and DVD-ROMs 40, and freelydistributes them to places where many Internet users gather such ascomputer shops, computer program shops, or computer book stores.

Further, the Internet broadcasting station 30 exceptionally andaggressively allows the users to reproduce the specific contents datafreely distributed on the Internet and the CD-ROMs without formalpermission 80 by the Internet broadcasting station 30, and promotesunauthorized reproduction 80 (transmitting and receiving data throughreproduction of CDs, DVDs, the Internet, etc.) so that the users mayreproduce the specific contents and share them with friends.

Also, the Internet broadcasting station 30 uploads contents data andspecific execution programs to the shared file directory 95 at any timeso that the many Internet users may use them freely and conveniently,and accordingly stores as much contents data in their HDDs as possible.

When the user attempts to use the contents, a use condition 60 isrequired. That is, the user must either pay for the contents or view acustomized advertisement sent by the Internet broadcasting station 30together with the contents. If not, the contents may not be used. Inorder to execute this complete control, the Internet broadcastingstation 30 converts the various programs provided by the authors intospecific contents data that the users may only use through a specificexecution program.

The authors are classified into several categories. The first author 15owns the first author's server, and the first author converts variousprograms possessed by the first author into specific data using thetechnique according to the present invention, and directly provides theconverted data to users through the Internet 50.

However, when the user uses the contents data, it is required for a userterminal to receive restoration information on the Internet 50. Thefirst author stores restoration information in a data storage unit ofthe Internet broadcasting station 30, and when the user executes aspecific execution program, the first author allows the user terminal toautomatically access the Internet broadcasting station 30 so as toobtain restoration information.

In order for the many users to use the author's programs and to get moreprofit, the first author stores the contents data on various recordingmedia including CD-ROMs and DVD-ROMs 40 and distributes them free ofcharge.

Also, the first author uploads the contents data and the specificexecution programs to well-known portal sites' shared file directories95 frequently to make them public so that many users may easily obtaindesired contents data.

The first author mostly includes big companies such as movie companies,television broadcasting stations, and huge publishers rather thanindividuals.

The second author 10 mainly includes small companies or individuals whopossess many authored pieces, and the second author 10 does not directlyprovide the contents data to the users, but uses the server of theInternet broadcasting station 30.

In the case of the first and second authors 15 and 10, the first fee andadvertisement profit manager 199 of FIG. 2 of the Internet broadcastingstation controls the computers of the first and second authors 15 and 10in real-time so that the authors may monitor the categories and thefrequency of use of the contents used by the users, and so they may knowhow much in fees and advertisement profits are deposited, in real-time.

Further, the first fee and advertisement profit manager 199 supports theauthors to check the programs' popularity, that is, the frequency ofuse, with graphs for each time and day so that the authors may refer tothem for publicity campaigns and program production and planning, andproduce better programs with reference to them.

The third author 18 generally includes very small companies orindividuals who have several programs, and in this case, the thirdauthor sells the programs possessed by the third author to the Internetbroadcasting station by one-time allowance or by installment.

In certain cases, some companies or individuals may provide theirprograms free of charge so as to widely promote or propagate theirworks. For example, singers frequently release their music videos so asto publicize their songs.

FIG. 2 shows a block diagram of an Internet broadcasting contentsconsignment sale system (in other words, an Internet broadcastingstation) according to a preferred embodiment of the present invention.

The Internet broadcasting station 200 is connected to a user terminal100 and a contents provider 300 through the Internet 110.

The Internet broadcasting station 200 comprises: a first web server 130;a first CD and DVD producer 140; a program manager 150; an advertisementdata manager 160; a member and use information manager 170; a programand advertisement data producer 198; a first fee and advertisementprofit manager 199; a contents data management server 180; and a datastorage unit 190.

The contents provider 300 comprises: a second web server 310; a contentsdata manager 320; a second contents database 330; a second CD and DVDproducer 335; and a second fee and advertisement profit manager 340.

The first web server 130 performs a web access function for a pluralityof user terminals 100 to access the contents provider 300 through theInternet 110, and it transmits various contents data, correspondingrestoration information, and specific execution programs provided by theInternet broadcasting station 200 to the user terminal 100.

The program manager 150 provides a specific execution program to theuser terminal 100. The specific execution program is needed for usingthe contents when the users desire to do so after they freely downloadvarious contents data such as movies, music videos, comics, and novelsthat are produced in a specific manner to their computers from theInternet broadcasting station, to collect them and store them.

In order to use the contents data, users all over the world registerthemselves to the Internet broadcasting stations, download the specificexecution program to their computer 100, and install the same.

When the user attempts to use the downloaded contents data, it isrequired for the user either to pay the fee for using the contents or toview the advertisement together with the contents, and when the useraccordingly selects to view the advertisement together with the contentswithout paying the fee, the advertisement data manager 160 transmits acustomized advertisement that creates the best advertisement impacts tothe user terminal 100 using member information.

In this instance, since the customized advertisement is well known topersons skilled in the art, no corresponding description will beprovided. In some cases, the user is required to pay a predetermined feedepending on the categories of the contents such as new-release moviesand recent music videos.

The member and use information manager 170 manages all kinds of memberinformation provided when the Internet users register on the Internetbroadcasting station, and manages the categories of the contents datadownloaded by the members, the frequencies of use on the contents data,categories and frequencies of use of the advertisement data viewed bythe members, and fee history for each time and date.

The contents data management server 180 comprises: an important datamanager 181 for separating an important portion from the contents data,and transmitting the important portion as restoration information; anediting code manager 182 for generating editing codes of the contentsdata, and transmitting the editing codes as restoration information tothe user terminal 100; a numerical value manager 183 for converting thenumerical values of the contents, and transmitting the numerical valuesfor restoring the converted numerical values into an original format asrestoration information to the user terminal 100; a contents dataconverter 184 for converting various programs (or contents) consigned bythe authors into specific contents data, and transmitting them to theuser terminal 100; and a contents introducer 185 for generatingdescriptions of the contents, transmitting the descriptions to the userterminal as restoration information, and when a request for transmittingthe contents data or a request for using them is provided by the userterminal 100, enabling the user terminal to receive the requestedcontents data and corresponding restoration information.

The data storage unit 190 comprises: a program database 191 for storingspecific execution programs; an advertisement database 192 for storingvarious advertisement data; a member and use information database 193for storing member and use information; an important data database 194for storing important data; an editing code database 195 for storingediting codes; a numerical value database 196 for storing numericalvalues; a contents data database 197 for storing the converted contentsdata; and a contents database 185-1 for storing description data forintroducing the contents data, and storing restoration informationcorresponding to the contents data.

The program and advertisement data producer 198 produces a specificexecution program and various advertisement data and uploads them to theprogram database 191 and the advertisement data database 192.

The first fee and advertisement profit manager 199 calculates allnecessary items in real-time such as date, time, number of times, andwhat categories of the contents data the user uses, how much the userpays for the corresponding fee, how many times and what advertisementthe user views, how much advertisement income and use fees aregenerated, and how much the total profit is. The first fee andadvertisement profit manager 199 controls computers of the contentsproviders 300 and analyzes in detail how much earnings are generatedafter the prior settlement up to the present state, and notifies thesecond fee and advertisement profit manager 340 of analysis results inreal-time.

The CD and DVD producer 140 records promotional contents data onCD-ROMs, DVD-ROMs, and other huge-volume recording media so that theInternet broadcasting station may lead more users to utilize thecontents data.

The free-of-charge distributor 120 includes computer shops, softwareshops, or computer bookstores where the Internet users may get CD-ROMsor DVD-ROMs that contain the above-noted contents data free of charge.

The contents provider 300 comprises a second web server 310, a contentsdata manager 320, a second contents database 330, a second CD and DVDproducer 335, and a second fee and advertisement profit manager 340.

The second web server 310 allows the user terminals 100 of the Internetusers all around the world to access the contents provider via theInternet 110.

The contents data manager 320 transmits the contents data provided bythe contents provider to the user terminal 100.

The second contents database 330 stores great volumes of contents datathat the users may download to their computers on the Internet oracquire them through recording media such as CD-ROMs or DVD-ROMs.

The second CD and DVD producer 335 records on the recording media thecontents data that are provided to the users for the promotional purposethrough the free-of-charge distributor 120.

The second fee and advertisement profit manager 340 receives signal datafrom the first fee and advertisement profit manager 199 of the Internetbroadcasting station 200, and allows the contents provider to monitorhow much earnings are gained, what contents and how many times the usersuse, how much in fees the users pay for viewing the contents, how manyusers view the advertisements and use the contents, and the users'frequencies of use on the respective contents by time and by date.

The user terminal 100 includes: a notebook computer or a desktopcomputer used for homes, offices, factories, and schools; a servercomputer supporting wire or wireless Internet; a wireless Internetportable phone terminal; a wireless Internet PDA terminal; and awireless Internet multimedia terminal (a transformation of a personalcomputer) installed in a car.

An operation of the specific execution program in the Internetbroadcasting contents consignment sale system (referred to as anInternet broadcasting station hereinafter) will now be described withreference to FIG. 3.

First, the user downloads various desired contents data provided by theInternet broadcasting station 200, the contents provider 300, thefree-of-charge distributor 120, or friends to an HDD of the user'sterminal 100, receives the contents data from them via CD-ROMs, orreproduces them to save them in the HDD of the user's terminal 100.

When attempting to use the contents data downloaded from the Internetbroadcasting station, the user receives a specific execution program andinstalls the same in the user terminal 100.

When the specific execution program is performed in the user's terminal100 in step S500, a CPU (central processing unit) of the user computerinitially checks a connection state to the Internet in step S510.

When the Internet is not connected, the user terminal 100 issues a firstwarning to access the Internet in step S520, and terminates the currenttask in step S650.

In this instance, when it is connected, the user computer accesses theInternet broadcasting station 200 in step S530.

Next, the user selects whether to execute the previously downloaded andstored contents data or to download new contents data in step S540.

Here, if the CPU of the user terminal 100 has a very fast processingspeed and the Internet has a very fast transmission speed, the user mayselect both methods at the same time, but in the present embodiment, theuser is assumed to select one of them.

Initially, in order to execute the downloaded contents data, the userselects the option of contents execution.

The user selects desired contents from among the contents datadownloaded and stored in the HDD, or transmitted through the CD-ROMs orthe DVD-ROMs in step S550.

The operation of the user terminal 100 when the user attempts to selectdesired contents will now be described.

Each time the user clicks the title of the contents data stored in theHDD, the CD-ROM, or the DVD-ROM, the user terminal 100 receives datacorresponding to descriptions of the contents data from the contentsintroducer 185 of the Internet broadcasting station in step S560, anddisplays a brief description together with images of important scenes.Therefore, the user refers to them to select desired contents data byclicking a mouse button twice.

When the user inputs an ID and a password that are provided to the userwhen the user performs the membership entrance, the member and useinformation manager 170 performs a use-allowance process to find whetherthe user is a registered person in step S570.

When the user's membership is confirmed, the user terminal 100 searchesdata of the restoration information corresponding to the contents dataselected by the user from the contents introducer 185, and receivescorresponding restoration information from the contents data managementserver 180 in step S580.

The actual restoration information includes editing codes, numericalvalues, and important portion data, and it may include one, two or allof them according to categories of the contents, and it is preferable touse all of them so as to prevent hacking.

The member and use information manager 170 asks a settlement method ofthe user when the user terminal 100 receives the restorationinformation. That is, the member and use information manager 170provides the user with options such as paying the fee through a creditcard or other methods, and viewing the contents together withadvertisements.

In this instance, when the user selects the option of viewing thecontents together with advertisements, the advertisement data manager160 transmits the restoration information including the advertisementdata to the user terminal 100, and the user terminal 100 receives themand stores them in the HDD.

It is preferable to temporarily store other restoration informationexcept the advertisement data and the contents data not in the HDD butin a RAM so as to immediately and automatically delete them after use.

When the corresponding settlement is finished, the user terminal 100receives the restoration information in step S580, and converts thestored contents data into contents data of before conversion andimmediately executes them in step S590.

When the user selects a temporary pause, the user terminal 100automatically deletes restoration information excluding theadvertisements so as to prevent incursion by hackers. When the userexecutes a “play” instruction again, the user terminal receives therestoration information again, and executes the contents data from thepause point.

If detecting a copy instruction for hacking, or other kinds of taskinstructions while executing the contents data, the user terminal 100stops all executions, deletes the restoration information, andimmediately terminates the operation in step S650.

When the execution of the contents data is finished, the user terminal100 checks use information such as categories and number ofadvertisements viewed by the user while viewing the contents, whetherthe user pays the fee for using the contents, how many hours and timesthe user uses the contents in step S610, and when the contents arecompletely executed, the user terminal 100 terminates the contents-usingservice in step S620.

Next, the user terminal 100 transmits the use information checked duringthe above stage to the member and use information manager 170 of theInternet broadcasting station 200 in step S630.

When the user's use allowance is rejected in the previous step S570, themember and use information manager 170 allows the user to enter themembership and use the corresponding service, it notifies the user ofthe incorrect ID and password and to check them again, it describessettlement methods, or it issues a second warning message that matchesthe corresponding situation in step S600, and then it terminates theoperation in step S650.

In the case of using computer game programs or business programs, whenthe use allowance step S570 is finished, the user terminal 100 executesthe contents data in step S590 to start a computer and video game or abusiness program.

Next, the user terminal 100 combines the restoration informationreceived after checking the membership with the game program or thebusiness program to convert the modified or incomplete game program orbusiness program into a normal program and execute the same.

The user terminal 100 checks the use information in step S610 in theidentical manner of other contents when the game program or the businessprogram is finished, and the steps S620 and S630 are performed, and theabove process is terminated in step S650.

However, in the case of a game program, the game may be finished oncewithin a very short time period in the contents data execution stepS590, and accordingly, the time and the execution of the game may belinked together.

In other words, if the user easily finishes the game in a minute, theuser is allowed to execute the game for a further several times forabout 30 minutes without performing the step S570 of use allowance, andif the user is playing a game when 30 minutes elapses, the use of thegame program is terminated in step S620 when the user finishes the game.

However, these items (e.g., use time, use number, etc.) may bedetermined or varied according to autonomous business policies of theInternet broadcasting station 200.

On the other hand, when desiring to receive new contents data in theselection step S540, the user may access the Internet broadcastingstation's homepage to select desired contents data from among variouscontents data in step S660 and freely download them.

In this instance, when the user clicks the desired contents' name, theuser terminal 100 receives a description of the corresponding contentsfrom the contents introducer 185 in step S670, and introduces thecontents to the user so that the user may adequately select desiredcontents.

The user then selects again in step S665 whether to only download thecontents data or to download the contents and view them concurrently.

An operation of downloading only will now be described.

The user clicks the name of the desired contents data twice, and thecontents data converter 184 loads corresponding contents from thecontents data database 197 and downloads them to the user terminal 100in step S680.

Also, while the user terminal 100 downloads the contents data, theadvertisement data manager 160 transmits advertisement data to the userterminal 100 as restoration information in step S670, and the userterminal 100 executes them to display a moving picture advertisement ona screen in step S690.

In this instance, the number and categories of advertising areestablished according to the Internet broadcasting station's businesspolicies.

When the downloading is finished in step S700, the user terminal 100transmits to the member and use information manager 170 information suchas the category and the number of the downloaded contents and theadvertisement data executed during the downloading in step S710, andterminates the downloading in step S650.

When attempting to use the contents while downloading the same in theselection step S665, the user is initially required to receive a useallowance in step S720.

Here, the user inputs an ID and a password given to the user at the timeof membership entrance. When the user's membership is confirmed, theuser terminal 100 finds data on the restoration informationcorresponding to the contents data selected by the user from thecontents introducer 185, and receives corresponding restorationinformation from the contents data management server 180 in step S722.

The user terminal 100 starts to receive the restoration information andasks a settlement method of the user to find whether the user will paythe fee for using the service or if the user will view the contentstogether with the advertisement, and in the case of paying the fee,whether the user will settle the same using a credit card or withanother settlement method.

In this instance, when the user selects to view the contents togetherwith the advertisement, the user terminal 100 receives the advertisementdata as restoration information and stores the same in the HDD.

The restoration information comprises important portion data, numericalvalues, editing codes, advertisement data, and contents descriptiondata. The remaining restoration information excluding the advertisementdata and the contents description data is preferably stored not in theHDD but temporarily in the RAM, and it is deleted immediately after itis used. When the settlement is finished, the user terminal 100 receivesrestoration information in step S722, and uses the editing codes tovirtually form a data file that has a time (frame) and a formatidentical with those of the actual contents data, and store them in theHDD in step S723.

The user terminal 100 uses the editing codes to receive the contentsdata selected by the user from the contents data management server 180of the Internet broadcasting station 200 in the actual order and sectionby section, and it edits them and arranges the same in disorder into avirtual moving picture file generated in the user terminal's HDD in stepS724.

When the contents data are stored to a certain extent, the user terminal100 executes the contents data in step S725. That is, the user terminal100 displays the advertisement, and adds an editing code, a numericalvalue, and important portion data to execute the contents data as ifthey are an original program.

When the user temporarily pauses execution of the contents data whilethey are reproduced, the user terminal 100 deletes virtual files andrestoration information except advertisement data and contentsintroducing data so as to prevent attacks by hackers, if any.

When detecting a copy instruction or other kinds of task instructionsfor the purpose of reproduction and hacking while executing the contentsdata, the user terminal 100 deletes restoration information exceptcontents introducing data and advertisement data, stops all the currentexecutions, and terminates the process in step S650.

When the execution of the contents data is almost finished, the userterminal 100 checks in step S726 for all kinds of use information suchas categories and iteration number of advertisements viewed by the usertogether with the use of the contents, whether the user uses thecontents after paying the fee, and how many hours the user uses them,and when the execution of the contents data is completely finished theuser terminal 100 terminates the use of the contents data in step S727and it transmits use information checked during the current operation tothe member and use information manager 170 of the Internet broadcastingstation 200 in step S728.

When the use allowance is rejected in the use allowance step S720, theuser terminal 100 displays the rejection reason about the use allowanceon the screen in a message format, generates a third warning message instep S721, and terminates the operation in step S650.

As shown in FIG. 4, the configuration of the restoration informationdescribed above comprises editing codes, numerical values, contentsdata, important data, and advertisement data, and the configuration maybe added, deleted, or modified if necessary.

FIG. 5 shows an example for applying the Internet broadcasting stationto a configuration of a relay broadcasting system, and a method forperforming relay broadcasting will now be described in detail.

When attempting to execute the specific execution program at the userterminal 100 in the case of applying the relay broadcasting system, theuser is initially required to register for a membership to the relaybroadcasting station 980 before installing the specific executionprogram.

When the user operates the installed specific execution program, theuser terminal 100 accesses the relay broadcasting station 980 to receiveall contents data, be permitted to obtain a use allowance, receiverestoration information, and settle the fee to the relay broadcastingstation to use all categories of contents. The Internet broadcastingstations 910 to 930 may not necessarily possess their own homepage, buthave a contents data storage unit and a restoration information datastorage unit. The relay broadcasting station 980 directly manages allusers' member and use information, and the users may receive allcategories of contents data provided by a plurality of Internetbroadcasting stations through a single homepage of the relaybroadcasting station, obtain a use allowance, and receive restorationinformation. The relay broadcasting station 980 receives settled usefees on the contents data from the users, keeps a predetermined portionas commission, and provides remaining portions to the respectiveInternet broadcasting stations 910 to 930 that provide the contents datadepending on the used amounts of contents data.

Also, when desiring to receive monthly membership fees from the manyInternet broadcasting stations and the specific execution program usersinstead of relaying the contents data, the relay broadcasting stationallows the Internet broadcasting stations all around the world to usethe method according to the present invention, provides technicalsupport, and in return receives a predetermined portion of sales as aroyalty.

Further, the relay broadcasting station may allow the Internet users touse the specific execution program and receive a predetermined portionof money each month as a program use fee (determined by the relaybroadcasting station according to national incomes, such as 5 dollars inthe U.S., and 2000 won in Korea.)

To achieve this method, a relay broadcasting station is provided, andall the specific execution programs are configured to be executed whenthe user is registered to the relay broadcasting station and installsthe execution program. Each time the execution program is executed, theuser terminal 100 initially checks whether the user is a registeredmember who accessed the relay broadcasting station on the Internet andhas paid the membership fee or an unregistered member who has not paidthe membership fee, and allows the program to be executed for theregistered member.

In this instance, the Internet broadcasting stations 910 to 930 comprisean Internet broadcasting contents consignment sale system of FIG. 2 forproviding the Internet broadcasting service according to the presentinvention.

The terminal in which the specific execution program is installed asshown in FIG. 3 comprises a wireless PDA 940, a wireless Internet mobilestation 950, a wireless Internet multimedia terminal 960 for vehicles, auser terminal 970, an Internet set-top box A 973, and an Internetset-top box B 976.

The above-noted terminals are wire or wirelessly connected to the relaybroadcasting station 980 on the Internet 900. The user terminal 970comprises desktop computers used for offices, homes, factories, andother places, notebook computers, and various kinds of servers. TheInternet set-top box A 973 may generate high-quality outputs throughoutput ends such as a VHS end, an S-VHS end, a DV end, and an HDTV end,and it may be used for general or commercial purpose so that the usersmay view various moving pictures or play video games or various computergames at home, in the office, or in a game room. The Internet set-topbox B 976 enables a premium, wider, and magnifiable screen so that itmay be combined with a professional big video projector for businesspurpose only, and it may display moving pictures such as movies or musicvideos in a small theater. When high-performance graphic cards andhigh-performance wide-screen projectors are released that are muchbetter than the conventional products, movies manufactured by filmmakersmay also be converted to contents data and transmitted on the Internetin the like manner of the Internet broadcasting stations, andaccordingly, theaters all over the world may receive them on theInternet, convert them into original contents data using the specificexecution program, and show them on the screen, thereby building a bigtheater system. Therefore, the film industry will no longer use filmpacks, and premium quality movies that do not deteriorate even afterrepeated use or a longer time has passed may be shown. The filmmakersare then not required to directly distribute the movies to the theatersthrough a complex distribution structure, and since the theaters and thefilmmakers together check movie screening numbers through computers,they may accurately and fairly share the profits.

For a further detailed description of the relay broadcasting system, thewire or wireless Internet users receive various categories of contentsdata from the Internet broadcasting stations A to C via the Internet orstoring/recording media such as CDs or DVDs.

When the user attempts to use contents data, a specific on-lineexecution program that is developed and distributed by the relaybroadcasting station is required, and when the user desires to use theexecution program, the user needs to install it and register as a memberto the relay broadcasting station on-line so as to use the same nexttime.

When the users execute the specific execution program, the user terminaloperates as follows.

When an Internet user receives desired contents data provided by variousInternet broadcasting stations all over the world from the homepage ofthe relay broadcasting station, and selects desired contents data fromamong them at the execution program, the user terminal reads a title ofthe selected contents data and immediately accesses the member and useinformation manager 982 through the web server 998 of the relaybroadcasting station 980 in a wire or wireless Internet manner.

The member and use information manager 982 searches the member and useinformation database 985 to check whether the user is a registeredmember who is authorized to use the execution program or an unregisteredmember, and settles the corresponding use fee. Next, the user terminalaccesses the contents manager 981 to find an address of the Internetbroadcasting station that provides the contents data selected by theuser, and accesses the Internet broadcasting station's server to receiverestoration information corresponding to the selected contents data.

When the user selects to view the contents data together withadvertisements without paying the fee, the relay broadcasting stationconcurrently reads the user's information from the member and useinformation database 985 to find customized advertisements that are themost appropriate for the user from the advertisement database 986, andtransmits several advertisements to the user terminal through theadvertisement provider 983 either once for all (from one to tenadvertisements) or slowly and with ample time while the user uses thecontents.

It is desirable to check the member information and transmission speedand transmit advertisement data of small data volume to a movingwireless Internet user and transmit those of big data volume to ahigh-speed wire Internet user.

In this instance, the user terminals 940, 950, 960, 970, and 973 receiveadvertisement data, concurrently find the Internet broadcasting station,access the Internet broadcasting station once the address is found,receive supplementary data, and execute the contents data as shown inFIG. 3.

Since the commercial Internet set-top box B 976 provides high-qualityimages and sounds that are excellent in comparison to those provided bythe general product, it is desirable to receive a use fee from the userand issue a use allowance each time.

It is more desirable to only receive a use fee except in advertisementviewing when doing business using the Internet set-top box A 973 in avideo room or a game room.

The Internet broadcasting stations A, B, C, . . . do not duplicate thetitles of the contents data when producing the contents data, and theyregister the address of the server that stores the contents data andrestoration information to the contents manager 981 of the relaybroadcasting station and store the address in the contents address andrestoration information address database 984.

The users are required to either pay the use fee each time the user usesthe contents data, or view the advertisements of the relay broadcastingstation together with the contents data when the user does not desire topay the fee. The use fee and the advertisements are varied according tothe contents data and determination of the relay broadcasting station.

The relay broadcasting station 980 stores programs for automatically andmassively producing specific contents data, the specific executionprogram, and all kinds of information needed for opening the Internetbroadcasting station according to the present invention on recordingmedia such as CDs, and provides them to the general Internetbroadcasting stations free of charge, or provides through the Internetthe above-noted specific contents-developing tool and all kinds ofinformation required for it to general Internet broadcasting stationsall over the world.

By cooperation with terminal makers, such as makers of various wirelessInternet mobile stations, wireless Internet PDAs, and wireless Internetmultimedia terminals for vehicles, the relay broadcasting stationdevelops specific execution programs that may be installed in theabove-noted makers' terminals.

The relay broadcasting station also develops varied versions of thespecific execution program for Internet users who use general IBM orMcIntosh platform computers, and distributes them to any users free ofcharge through the Internet broadcasting stations A, B, and C, variousportal sites' shared file directories, recording media such as CDs andDVDs, or default installations in newly assembled computers of computerassembling companies.

The wireless Internet mobile stations or the wireless Internetmultimedia terminals (a transformed PC) installed in the vehicle requireRAM capacity of at least 23M to about 128M (recommended capacity) so asto access the Internet broadcasting station and fluently use variousmoving picture services, and they also require free data communicationwith general computers via cables in the like method of the wirelessInternet PDAs.

In the case of using relatively short moving picture data such as musicvideos of about 3 to 5 minutes running time, as opposed to long movingpictures such as the movies, about 32M RAM may be sufficient.

In the case of using the Internet broadcasting system through a mobileterminal, the user may freely use the service with a very low feeaccording to the current packet fee system.

When the user desires to use the contents data, it is required for theuser to receive restoration information through the wireless Internetwhen the user has previously downloaded music videos or movie data to ageneral computer and stored them in the memory of a terminal such as aPDA through a data transmission cable. Accordingly, the user may use thecontents data at a very low cost with a clear screen and great sound andwithout distortion or interruption in a fast moving train or a car,compared to the conventional streaming method wherein the terminal iscontinuously connected to the Internet to receive all data during themovie running time (about 90 to 120 minutes).

Also, even when the user directly receives the desired contents datathrough the mobile terminal and uses them, they may download all datawithin a much shorter time compared to the actual movie running time,and accordingly the present invention requires less communication timewhen compared to the streaming technique. When the IMT2000 servicestarts, the user may receive data at 2M per second when the user isstationary, and hence, when assuming that the actual data transmissionspeed is about 1M per second, that is, a half of the standardtransmission speed of 2M, the user may download the volume of a singlemovie (about 90 to 120 minutes of running time) in 3 to 7 minutes sincethe screen size of the moving picture data used by the wireless Internetmobile stations, PDAs, or multimedia terminals for vehicles is small andthe corresponding total data capacity is also small.

Therefore, the users may save on communication fees by reducingcommunication time, and they use the terminal less frequently so thatthe battery installed in the terminal is used less, so the terminal maybe used longer. Internet users may collect and keep desired contentsdata for respective categories and subjects of entertainment accordingto their interests, as they desire.

As described above, in the preferred embodiment of the presentinvention, users may freely receive various desired contents such asmovies, music videos, dramas, comics, novels, photo albums, computergames, or video games according to their interests from an Internetbroadcasting station or through recording media such as CD-ROMs andDVD-ROMs distributed by the Internet broadcasting station free ofcharge, collect and keep them, and use them at any time.

Since the users execute most of the contents previously downloaded, theusers may execute various contents with top image and sound qualities(e.g., DVD quality) and at any time without being greatly interferedwith by interruptions caused by heavy Internet traffic.

In particular, the users may freely use the moving picture service suchas for movies or music videos with good image and sound qualities in afast moving train, a subway, or a car, using the wireless Internetmobile station or PDA with a very much lower communication fee. Theusers may also receive various quality moving picture services such asfamous films, music videos, dramas, plays, and sitcoms with good qualityimages and sound through the Internet in a fast running car on anexpressway using the wireless Internet multimedia terminal installed ina car.

The contents data downloaded to the users, such as movies or novels, areexecuted on the specific execution program, and the users are requiredto initially access the Internet broadcasting station through theexecution program and obtain a use allowance so as to use the contentsdata, and the Internet broadcasting station either receives the use feefrom the user or sends customized advertisements to the user terminalfor each issuing the use allowance, and accordingly, the Internetbroadcasting station earns corresponding advertisement profits,completely manages and controls the users, and provides effectiveadvertising, thereby gaining much profit from the use fees andadvertisements.

Further, illegal program reproductions frequently occurring on theInternet because of charging for contents may be prevented by providingthe users with a huge amount of diverse contents data including moviesand computer games free of charge, allowing the users to collect andkeep them according to their interests, allowing the users to freely usethem when viewing the contents together with the advertisements providedat the start, the middle, and the end of the contents data, and fullysatisfying the users' possessiveness. (Some contents require the usersto pay a predetermined fee.)

Since the various contents data provided by the Internet broadcastingstation through a free downloading service are converted according to aspecific conversion method, when reproducing them and attempting to usethem, the users need to connect the user terminal to the Internetbroadcasting station through the specific execution program and obtain ause allowance to use the contents data, and therefore the Internetbroadcasting stations and the authors who have copyrights of variouscontents may provide and distribute their programs to users on theInternet, with no more fear of illegal reproduction. Rather, they mayhope that Internet users all around the world reproduce their programsthrough legal or even unauthorized reproduction processes, collectdesired ones, keep them, and use them everyday.

When using the conventional streaming method to view the moving picturesthrough a mobile station, it is required for the user to operate themobile station and be connected to the wireless Internet for two hoursto view a movie with a 2-hour running time, but the present inventionenables the user to previously receive desired data in a shorter timeframe, store the same, and then view the movie, and accordingly the usermay greatly reduce the time for using the wireless Internet and the timefor using a battery of the terminal, thereby allowing a longer usingtime than with the conventional streaming method.

If the IMT200 standard supports a data transmission speed of about 2Mper second as announced, the user may store most kinds of data in theuser terminal (wireless Internet mobile station or PDA) in 3 to 7minutes after connecting to the wireless Internet.

Hence, even when the fee system for the Internet mobile terminal (e.g.,an IMT2000 terminal) is changed to that of the general mobile terminal,the use fee is greatly reduced, and further, the user may use thecontents only if the user receives restoration information andsupplements it when the user has previously received most of thecontents data, and accordingly, the user may use high-quality movingpicture services in a fast moving train or a subway as desired.

While this invention has been described in connection with what ispresently considered to be the most practical and preferred embodiment,it is to be understood that the invention is not limited to thedisclosed embodiments, but, on the contrary, is intended to covervarious modifications and equivalent arrangements included within thespirit and scope of the appended claims.
